In this short note I shall address a problem of word order in a passage of Petronius’ Cena Trimalchionis by pointing out an attractive variant in the key codex Traguriensis, which has been neglected thus far.
During the dinner, a fierce quarrel between Trimalchio and his wife Fortunata breaks out. Habinnas, the guest of honour of the Cena and good friend of the master of the house, tries to calm them down. Here is the text printed in all Petronian modern editions (Petron. Sat. 75.1–2), with the critical apparatus of K. Müller's fourth edition and the translation by P.G. Walsh:Footnote 1

This thunderbolt led Habinnas to start begging Trimalchio to cool his temper. ‘We all make mistakes,’ he said. ‘We are human, not gods.’ Scintilla too spoke in the same vein through her tears […]
I shall concentrate on Habinnas’ words and, in particular, on the position of non as it is transmitted by our witnesses. Our primary witness for the Cena, the Traguriensis (Par. lat. 7989: H), transmits the whole passage. For passage 75.1, in the excerpta longa (L) and the Florilegium Gallicum (φ), we find only the sentence nemo … dei, as indicated by the vertical bars and the marginal indications in Müller's edition. Beside the omission of inquit in Lφ (an element not reported in Müller's critical apparatus),Footnote 2 the only other difference in the text is the position of non (nostrum non Lφ : non nostrum H). Of course, the different word order does not affect the meaning of the sentence: with both readings we have a double negation (nemo + non) signifying ‘everybody’.Footnote 3
Most of the previous editors of Petronius’ text (with very few exceptions) print nostrum non, even though they knew the reading of the Traguriensis, doubtless because they were influenced by the word order that was already known from the excerpta longa. Footnote 4 F. Bücheler, the first modern editor of the Satyrica, prints nostrum non and annotates in the critical apparatus ‘non nostrum transponit H’, as if there were something wrong in the word order of the Traguriensis. Footnote 5 As often happens, all modern editors follow Bücheler and endorse the reading of L and φ instead of the reading of the Traguriensis. On what grounds was the reading of H discarded by almost all editors? It is not at all clear. Some Petronian commentators quote the different word order of H, but do not analyse the problem in detail.Footnote 6 I suspect that the reason is that the position of non in H is perceived as unnatural—but, as I shall demonstrate, this is a misconception.
First, the variant nemo … non nostrum is acceptable and the following parallel, among many others, demonstrates that this syntagm is absolutely normal. Seneca (Controv. 10.4.4) writes:Footnote 7
puto, expertus es nos non esse crudeles; tamen nemo non nostrum, cum istis stipem porrigeret, mortem precatus est.
I think you know by experience that we are not cruel: yet every one of us, when holding out alms to these wretches, prayed they might die.
The position of inquit in the Petronian passage does not constitute an obstacle to the reading of H.Footnote 8 It suggests, rather, that the position of non in H, between inquit and nostrum, could be considered, at least to a certain extent, as lectio difficilior.
Second, if we consider the complex manuscript tradition of the passage, we have a definitive confirmation that the text of L and φ represents a banalization and that H offers a sound reading. In fact, L and φ are not reliable on this point, since, for this section, they are not transmitting the whole text, but only an anthology of excerpted sententiae. As has been said, inquit has been cut out: another intervention of the excerpter on the position of non would be a quite plausible scenario.Footnote 9 In what follows I shall offer a brief excursus on the tradition of the Cena and especially on the sententiae transmitted by L and φ in order to support my case.
H contains the whole episode (26.7–78.8): thanks to the Traguriensis we can identify the cuts and the original collocations of the excerpts in the other witnesses.
The so-called excerpta breuia (O) have only a reduced version of chapter 55 and, therefore, are not important for 75.1.
The excerpta longa (L) present a narrative block from the beginning of the Cena (27.1–37.5), with many cuts, followed by the reduced version of chapter 55 that we find also in O. Then L presents the ‘after-dinner episode’; at the conclusion of it, after a poem with a simile on Tantalus (82.5 non bibit …), L has seven sententiae from the Cena in the correct order (43.6, 44.17, 45.2, 55.3 vv. 1–2, 56.6, 59.2, 75.1). After this there is an isolated sentence (82.6).
φ has the poem with the Tantalus-simile (82.5 non bibit …) before the excerpts of the Cena. The first excerpt of the Cena is 34.10, a poem whose narrative context is attested to both by L and (obviously) by H. Then we find the seven sententiae from the Cena, in the very same order as in L. Below are the seven maxims (Müller's text and critical apparatus, with some integrations):

In the anthology attested to by L and φ the sententiae have undergone abbreviations and adaptations (elimination of connecting particles such as autem and enim and of the verb inquit; the addition of the subject apes). These changes are, of course, the consequence of a work of excerption; the presence of the continuous text of the Traguriensis enables us to detect the interventions of the excerpter. This common feature of L and φ prompted Helmut van Thiel to postulate that the hyparchetype L took the seven sententiae from φ. This is a thorny stemmatic issue, which I am not going to discuss in detail here.Footnote 10 Either L is relying on φ, or L and φ depend on a common source that contained the anthology of maxims: in both cases it is not advisable to prefer the reading of L and φ over that of H. More generally, it is worthwhile to note that the text of L is inferior to that of H, as Müller demonstrates precisely on the basis of examples of word order.Footnote 11
To conclude, let us come back to the sententia of 75.1. Petronian editors print a sort of mixture of the text of H and that of L and φ: they keep the inquit of H (of course!) and the position of non of L and φ. However, there is no reason at all to reject the position of non that we find in our most important witness for the Cena, H, especially if we consider that the text of L and φ is the result of an operation of excerption and rewriting (consequently, as has been said, the text of the seven sententiae of L and φ is of poor quality). This is a very instructive instance of the possible improvements on the text that could be brought about by a thorough reconsideration of the manuscript tradition.
